The bg was found on a bench inside the terminal at 10 am, prompting the officials to evacuate some 100 passenger from the terminal.
A military dog signalled that there was suspicious items in the bag.
Explosive ordnance disposal officers from the Ninth Infantry Division rushed to scene and shot the bag with a high-pressure water canon before they checked it and found that it was simply a school bag with text books and pencils. Police said carbon from the pencils might confuse the sniffing dog.
